| 摘 要： | 在川南古宋煤田富安井田上二叠统龙潭煤系勘探过程中，发现其底板阳新灰岩内深部岩溶发育。文章根据电网络模拟及水化学资料，建立了阳新灰岩的岩溶水系及其结构，并通过岩溶水系铀含量及同位素（２３４Ｕ及２３８Ｕ）组成的研究，进一步为分析分支水系补给区、径流区及排泄、混合区的水文地质特征及地球化学环境提供了依据

| Abstract: | The deep karst of Yangxin Formation Limestone, which is located on the bottom of the Longtan coal meassures of Upper Permian in the Fuan well field, was discovered by exploration. Based on electric network simulation and the data of water chemistry, the karst water systems are established in this paper. The content of uranium and isotope composition ( 234 U/ 238 U) in karst water are also studied. The results provide an important basis for assessing the hydrogeologic feature and geochemical environment in the rechange, run off and mixture areas of karst water. |
